Deciphering Bee Swarms: Understanding Nature's Phenomenon

Deciphering Bee Swarms Understanding Nature's Phenomenon


The sight of a massive, chaotic swarm of bees may understandably trigger alarm. Spring, in particular, marks the season when such swarms of honey bees are frequently encountered in seemingly random locations. But here's the thing—beekeepers assure us that these swarms are not to be feared. In fact, they are crucial for the future pollination of a significant portion of the food we rely on. Let's delve into why bees swarm and what actions you should—or shouldn't—take when you come across a mobile colony.

Unraveling the Mystery of Bee Swarms

Swarming is an integral part of the natural reproductive life cycle of honey bee colonies and typically occurs in spring as temperatures rise, and flowers begin to bloom. Honey bees, scientifically known as Apis mellifera, typically swarm for two primary reasons: when the hive becomes overly crowded or when they are compelled to leave due to the presence of pests or disease.

Mark Paterson, a seasoned beekeeper with nearly two decades of experience, explains that as the bee population grows, the old queen and about half of the hive depart to establish a new colony. This departure often involves the bees forming a clump on a tree or fence within 30 meters of the hive.

Mr. Paterson further notes, "They'll be sending out scouts looking in an area of up to 70 square kilometers looking for a new home." These scouts are engaged in a search for a suitable nesting site, which could be a tree hollow, possum box, or any cavity with a volume of at least 40 liters.

The Fascinating Role of Scouts

When the scouts return, they perform a distinctive figure-eight dance, with the dance's orientation indicating the direction in relation to the sun, guiding their fellow bees to the chosen location. The duration of tail-shaking in their dance determines the distance they must travel. Each second of tail-shaking signifies roughly 750 meters.

Mr. Paterson elucidates, "They'll do this multiple times to encourage other scouts to go and investigate the space that they've identified as a suitable home, and more scouts will go out."

In the meantime, the rest of the bees remain clustered around the queen, forming a protective ball. However, the bees may need to take breaks during their journey to the new location. The extended journey could be as far as 4 to 6 kilometers, a considerable distance for these insects. Sometimes, the queen needs to rest, which may lead to temporary stops during the migration.

What to Do if You Encounter a Bee Swarm

In most cases, Mr. Paterson reassures that bees are generally calm while swarming since they are laden with honey and have nothing to protect. However, if the queen bee is absent, which can happen if she is preyed upon by a bird, the swarm may become agitated.

If you notice a swarm of bees entering your yard, it's advisable to keep children and pets at a safe distance and allow the bees the space to assemble and form a cluster. Typically, swarms will move on after a few days.

Should you prefer the swarm to depart sooner or harbor concerns about them taking up residence around your property, contacting a beekeeper who specializes in swarm removal is the recommended course of action. Beekeeping associations and societies in each state and territory can provide lists of collectors who will gather the swarm at no charge or for a modest fee.

These collected bees are typically relocated to establish a new colony or, if they have lost their queen, are assimilated into another hive to bolster their numbers.

Dermot AsIs Sha'Non, a seasoned beekeeper with over 12 years of experience, emphasizes the importance of having a swarm collected, as it prevents them from settling in an undesirable location around your home. Removing a swarming cluster of bees is far simpler than extracting an established hive, which often requires invasive procedures like cutting into walls or removing bees from chimneys.

What to Avoid with a Bee Swarm

It's essential to refrain from attempting to disperse the swarm. Actions such as spraying the bees with water, using smoke, or throwing objects at them could agitate the insects, leading to defensive stinging. These actions also hinder the beekeeper's ability to safely remove the swarm.

Of utmost importance is to avoid using pesticides on the bees. As Mr. Paterson asserts, "Most of the time they will not be concerned about you; their only concern is to protect the queen." The best approach is to allow the swarm to go about its business undisturbed.

The Invaluable Role of Bees

Bees play an indispensable role in pollinating a wide variety of fruits, vegetables, and nuts. A staggering one-third of our dietary staples relies on pollination, which is predominantly performed by bees. As Mr. Paterson aptly puts it, "Bees are the most important species on this planet for the future of mankind." The absence of bees would have far-reaching consequences, affecting the availability of fruits and nuts, and ultimately disrupting food production.

To support bees and their vital role in our ecosystem, consider planting flowering plants in your garden and purchasing locally sourced honey. Bees have graced the Earth for approximately 25 million years and are well-equipped to endure. However, their disappearance would spell dire consequences for humanity.

Both Mr. Paterson and Mr. AsIs Sha'Non have noted a decline in bee swarms around Canberra, though the reasons remain uncertain. Varroa mite, a significant threat to bees, has not yet reached the Australian Capital Territory. Beekeepers are anxious about its impending arrival, as it has decimated wild colonies in other parts of the world. When wild colonies disappear, the impact on pollination services can be severe, potentially affecting food production and agriculture.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

  Non-contact exposure to dinotefuran disrupts honey bee homing by altering  MagR  and  Cry2  gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering  MagR  expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the  MagR  gene responded to magnetic fields only in the presence of light, with  Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

  “Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups.  Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

Start the New Year Humming Like a Bee

  Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The Essential Role of Bees in Our Ecosystem and the Challenges They Face

The Essential Role of Bees in Our Ecosystem and the Challenges They Face Bees have been an integral part of our ecosystem and human agriculture for over four centuries, primarily utilized for their honey in the early days. Now, they are recognized more for their critical role in pollination, which directly impacts a vast majority of the food we consume. Mark Lilly, a prominent beekeeper, emphasizes that without bees' pollination efforts, a significant portion of our diet would be at risk. However, bees face numerous threats, including varroa mites and, in specific regions like West Virginia, black bears. These challenges necessitate concerted efforts for preservation and protection. Frequently Asked Questions (FAQs) Q1: Why are bees so important to the ecosystem? A1: Bees are crucial for pollinating plants, which is necessary for the production of fruits, vegetables, and nuts. Without bees, a large portion of the food we eat would not be available. Q2: What are the main threats to...

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles As the number of pets in South Korea steadily increases, pet owners face a growing dilemma due to the limited number of pet cemeteries across the country. Under the current legal framework, pet remains are classified as household waste, requiring specific disposal methods that are neither convenient nor easily accessible for all citizens. The imbalance between the rising pet population—over 5.52 million households with pets by the end of 2022—and the mere 70 registered pet cemeteries has led to significant challenges. This shortage is particularly evident in regions like Jeju Island, where pet owners must undergo arduous journeys to the mainland to ensure their pets receive proper burials. The root cause of this shortage lies in the strict regulations governing the establishment of pet cemeteries. These facilities, which must include crematoriums, face numerous restrictions, such as proximity to resident...

Climate Crisis Claims Glacier's Vital Climate Data Archive

  Climate Crisis Claims Glacier's Vital Climate Data Archive A recent study published in Nature Geoscience reveals a distressing consequence of global warming: the irreversible loss of valuable climate data stored in alpine glaciers. The research, conducted by a team led by Margit Schwikowski from the Paul Scherrer Institute (PSI), underscores the alarming rate at which glaciers are melting and highlights the implications for climate research. The study focuses on the Corbassière glacier at Grand Combin in Switzerland, where ice cores drilled in 2018 and 2020 were intended to serve as vital climate archives. However, comparing the two sets of ice cores reveals a grim reality—global warming has rendered the glacier unsuitable as a reliable climate archive. Glaciers, renowned as climate archives, encapsulate valuable information about past climatic conditions and atmospheric compositions. The fluctuating concentrations of trace substances in ice layers provide insights into historica...

German election: Climate and environment take a back seat

  German election: Climate and environment take a back seat When the coalition government comprising the center-left  Social Democratic Party (SPD) ,  Greens  and neoliberal  Free Democratic Party (FDP)  emerged after the last German federal election in the fall of 2021, then-incoming Chancellor  Olaf Scholz  (SPD) did not object to being called the "climate chancellor." That was no surprise: the climate crisis had been a top issue during the election campaign. The new government made the fight against climate change a task for the Economy Ministry and appointed Vice Chancellor  Robert Habeck  from the Greens as its head. Three and a half years later, campaign speeches barely mention climate protection. The dominant issues are how to curb irregular immigration and how to boost Germany's sluggish economy. Skeptical view of renewable energy The head of the center-right  Christian Democratic Union (CDU) ,  Friedrich Merz ...
